# OpenAI introduces the Realtime API

> OpenAI introduced a public beta Realtime API for low-latency speech-to-speech applications. The release described streaming audio over WebRTC and WebSocket connections, realtime function calling, and a preview model. It also documented an initial developer path rather than a blanket readiness claim for every voice workflow.

## Engineering relevance

Realtime systems compress the time available for safety and recovery. Hypler should test interruption, consent, error handling, transcript policy, and escalation paths before deploying voice automation.
